A cunning predator: How Silver Fox preys on Japanese firms this tax season

Silver Fox, a threat actor, has resumed phishing operations targeting Japanese organizations during tax season. The campaign spoofs tax-related and HR communications, exploiting the seasonal context when employees routinely expect and open such correspondence without suspicion. This timing-based social engineering tactic significantly increases campaign success rates. Organizations in Japan should warn employees about unsolicited tax or HR emails, especially during filing season, and implement verification procedures for sensitive requests. No specific malware families have been attributed to this campaign, suggesting reliance on social engineering rather than malicious payloads.
